Gaussian two-way relay channel with arbitrary inputs
A two-way relay channel with independent parallel Gaussian channels between the relay and the two terminals is considered. Focusing on the decode-and-forward protocol, the second p...

Capacity Analysis and Power Allocation over Non-Identical MISO Rayleigh Fading Channels
Abstract— We analyze the capacity of a multiple-input singleoutput system over Rayleigh fading channels. The channels are assumed to be independent and non-identically distribute...

From Multi-Keyholes to Measure of Correlation and Power Imbalance in MIMO Channels: Outage Capacity Analysis
An information-theoretic analysis of a multi-keyhole channel, which includes a number of statistically independent keyholes with possibly different correlation matrices, is given. ...
